More Mods on feet for Li-Po cells

[rep001]

Just finished some mods to my RN,inspired totally by Matts R.P .The design of the feet is slightly different.I needed more battery power as the hitec 1000mah was getting a good beating on/off charge many times in an evening. First thing that pleased me was the extra stablility due to a much lower c.g. I have put the regulator in place of the old bat position,but have yet to hide the isolation on/off switch.Still lots to do but for the time being enjoy the pics.thanks !

Your robot looking good, I still really like the head.

Cool, do the standard motion/movements still work like walking or have you redesigned/programmed them?

Looking way cool and I also think that head is the best one I've seen on a RN1

sorry for late reply not been feeling to good.Yes the standard movements do all work.He struggles alittle with a hand stand due to the weight in the feet but because the voltage is regulated to 6v he manages ok.The biggest improvement is walking and running.This he now does with out falling etc much better all round really .
i will post some vid when i can.
thanks

Hi

What kind of regulator and cut off circut you have?

[rep001]

Hi
I am using a Duralite regulator which is only good for 18amps so i keep a close eye on things in certain routines.It has a built in low voltage cut off but i also am using a lipo saver board which has an led on it that lights when voltage is close to minimum.
I can find out the p.no's if you wish but i have thrown the headers away and removed the labelled heatshrink... Doh !!
hope it helps.

You should be fine with a 18A regulator I use a 5A reg on my KHR-2 and it dosn't even get very hot. It would have to be a special route that has all 18 servos on max current.

I use two 1800mha Lipo cells in the feet with a 7.5 amps regulator on my 22 dof KHR-1 and a low volt led warning system.
No problems.
